thankyou for your advise

can anyone please advise me if this the correct way or whether this will cause problems later. i am making a pithed roof and have got to the part where i need to lay the breathable membrane, only thing is i have already fixed the roof battens and now want to lay the membrane over the top of battens and then fixed tiles on top. they are standard vangaurd 83 interlocking roof tiles that will sit ontop of the membrane once its laid along battens. i know now the membrane should go under the battens but ive fixed battens now. so can i carry on the fix tiles now or does all battens need to be ripped up. thanks Margaret Read more: https://www.diynot.com/diy/threads/breathable-membrane-over-or-under-roof-battens.571964/#ixzz6w5f2rq2B

I think im just going to give up. I thought with underpinning and concrete and not going as far back now will be ok but clearly wont be.

Hi all. Pro dave, he is not digging 2m on the wall side, he has dug 1m on wall side and then will dig 2m down 5ft away from house.

Yes i cant afford a se otherwise i would have. The builder has ruled out digging as far back as i wanted it which was 5ft from window. He has said minimum has to be at least 8ft maybe 10ft from window and then a 3 block concrete retaining wall with 4 pillars, and concrete between retaining wall and the remaining soil. 4 rsjs At least 6 foot. Square hole dug. Starting from house wall corner which is 1m at house side and goes out and deepens to 2m. Same both front corner sides. One already almost dug out. Two similar holes in centre of house outside bay window. These holes will have concrete poured in and then have each rsj inserted into them and pushed into house as far as possible. And then concrete ontop.

Hi, they have already dug one metre down, as the picture shows. They just need to dig 2 metres down in the same hole adjacent. And there is no concrete base. Just two bricks coming out.

The builders duck down today to check what type of Foundation is underneath the house and as you can see it goes down and comes out about 2 bricks so they have decided to dig down 1m at the wall and 5ft out and then 2m down, fill with concrete then insert 6-ft 9inchx9inch RSJ and then fill ontop with concrete again. They will do this each corner of the house at the front and at two points in the Middle by the window

Thankyou so much

Ok thankyou all Will need to really reconsider this.

No there is no basement. I can see why you say i need a se. Im so confused reading this. I was just hoping to make a parking space for my mobility car And its just got confusing and complicated. Hopefully my builder friend will be able to build this without issue He did mention about puttinf in at least 6 drainage pipes about 1metre off the floor to deal with the water trapped behind the wall.

Ill have to do some research and hope to be able to find these blocks cheap enough not to blow my budget Likeni mentioned before, its 16ft wide so will i still need 25 of these blocks

As for dirt the builder has been taking soil so thats not an issue

These concrete lego blocks, where can i get these and how many will i need. The wall will be approx 16ft across. Was hoping to tarmac or slab..

And rough how much for those 25 blocks. From what i have read, most of the options i cant follow due to budget, but I feel this option is best for me and wont blow my budget. Im just building wall at the moment and will worry about rendering and etc later

Ok will do that. So i buy a few of these and plant them at foundation and then use normal concrete blocks to build up?

I appreicate that prodave and you have been very helpful. You asked for measurements before, which i have now posted. Would 4ft to 5ft sound about right Im going to proceed with caution

I dont thing that story related to me. I do have a builder who will come a build the wall. I suspect everyone is assuming i was going to try myself. He has already said it will be around 9ft high with 3 ft buried for foundation and has said he has been building extentions for a long time. I suspect the way im going to go is carry on digging but instead leaving 4 ft between retaining wall and bay wall, ill leave 5ft. Double block the wall, with columns each side. And then a wall of concrete between wall and soil

Also a neighbour just told me i would need a 12ft wall with 3ft buried as foundation. He said he didnt think the ground infront is supporting the houses and in fact the houses have deep foundation and therefore we can go back as far as we want but then the retaining wall has to be thick and strong. He advised a 12ft wall with 3ft buried, so 9ft wall. As for the actual wall, double blocks, laid flat as opposed to stacked, and then concrete filled between the wall and ground behind. At least 8 pipes for drainage.

If you look at last 2 pics you can see the blue rope going from bay window wall across to lampost. Kept tight to give a straight line and then measurement taken down which was 9ft.

Hi thanks all for advice. Budget wise is only a few hundreds for parts. All labour is free as my neighbours and brother in law is helping me. I respect your advice on here and if its the case i need a se then ill have to give up and stop everything. And leave the front as it now. Prodave, i have taken the measurements you have asked for. So from the top at the bay window, to the bottom at the boundary line, ensuring it stays high and level and straight, the distance was 29ft As for how high, i used a rope, tied to bottom of wall at bay window and ran down straight and tied it to the lamppost adjacent to front of house and then used a spirit level to check rope was straight and then messaged from rope down to footpath at boundary. On one side it was 9ft high and the other was 7.4ft high. And thats because of slope of fooftpath. So 29th length from bay wall to boundary And max height is 9ft.

The pallet i have already bought are 440mm, 240mm, 100mm Which are just standard concrete blocks Ive also got 10 wider ones. Will these not do the job?

You say buttress sections, can you explain please what that means. And what did you mean the two ends turned in? Our plan was to turn out away from house to make a u shape.

ProDave, yes exactly that, lol can you recall how much distance between the front of the house and the retaining wall you put in.
